45 <h3>Relevant Struct Members</h3>
47 <dt><i>version</i></dt>
48 <dd>Vorbis encoder version used to create this bitstream.</dd>
49 <dt><i>channels</i></dt>
50 <dd>Int signifying number of channels in bitstream.</dd>
52 <dd>Sampling rate of the bitstream.</dd>
53 <dt><i>bitrate_upper</i></dt>
54 <dd>Specifies the upper limit in a VBR bitstream. If the value matches the bitrate_nominal and bitrate_lower parameters, the stream is fixed bitrate. May be unset if no limit exists.</dd>
55 <dt><i>bitrate_nominal</i></dt>
56 <dd>Specifies the average bitrate for a VBR bitstream. May be unset. If the bitrate_upper and bitrate_lower parameters match, the stream is fixed bitrate.</dd>
57 <dt><i>bitrate_lower</i></dt>
58 <dd>Specifies the lower limit in a VBR bitstream. If the value matches the bitrate_nominal and bitrate_upper parameters, the stream is fixed bitrate. May be unset if no limit exists.</dd>
59 <dt><i>bitrate_window</i></dt>
60 <dd>Specifies the size of the bit reservoir in seconds relative to the nominal bitrate. May be unset.</dd>
61 <dt><i>codec_setup</i></dt>
62 <dd>Pointer to private encoder setup state.</dd>
